Newton-Raphson number squaring method/pointers

Hello and thank you for any that reads this...

Another 12 to 16 hours can be spent and my useless implementation of the Newton-Raphson method
is still not going to work. Can anyone please tell me how to proceed? My complete program is written below.
The reason for the excessive use of pointers is due to an assignment requirement to utilize pointers as much as possible.

For those unfamiliar, the Newton-Raphson method simply squares a number with the degree of accuracy specified by a user, so if the number 100 is entered, the output should be 10 etc.

I sincerely appreciate any help and best regards to anyone involved with this site...

Hello zen,
Thank you very, very much for spending your time and correcting an admitted idiot's program. Since words are often abused I can only assure you that I appreciate your help with all sincerity...
